How to Map Network Drives in Windows


  • Map a network drive on a Windows 10 computer.


  • Windows 10 Operating System
  • Connection to the Mass General Brigham computer network (Ethernet, PHSWifi3, CVO or VPN)


Mass General Brigham builds Windows 10 computers automatically map drives when connected to the network, such as being onsite or being connected to VPN. 

Personal Windows PCs do not map drives directly.


If the drives are not mapped, you can manually map them. Manually mapping is required for Research Network Drives such as RFAs or MAD storage.
